He was seen in the Throne Room of Caemlyn Palace when Lord Gaebril was active in Andor. After Rand al'Thor enters Caemlyn and defeated Gaebril, he seemed to have become a little addled.
A group of nobles including Arymilla, Elenia, Jarid, Karind, Naean, Lir, Henren, Carlys, Daerilla, Elegar, and Lord Nasin watches Rand practice the sword against five men in a courtyard of the Royal Palace in Caemlyn. Nasin tells Rand he is another Jearom. Lord Nasin gasps and panics when Taim is lead into the courtyard.
He initially supported Arymilla Marne for the Lion Throne. He seems to believe that Elenia is his betrothed and fawns over her and that Arymilla is his daughter.
With the support of Elenia, Naean and Nasin, Arymilla brings four armies to lay siege to Caemlyn.
Arymilla dines with Naean, Elenia, Karind, Lir, Nasin and Sylvase to prepare the last attack.
According to his grand-daughter, Sylvase Caeren, he died of a fit just before Arymilla's forces were defeated during the Siege of Caemlyn. This seems suspiciously convenient. Sylvase is considered ruthless by Elayne, she thinks the girl has a very hard core. Probably she somehow during the battle killed her grand-father, though Elenia also may have been behind the death as previously she was considering whether to kill him or Arymillia first .
